In the embodiment illustrated the vehicle frame 1 is shown mounted onthe usual front and rear wheels 2 and 3 and comprising side bars 4'and5braced and connected in the usual manner. The brake constituting thisinvention in- 4 eludes transversely arranged rods 10 and 11 spacedlongitudinally from each other and mounted in the side bars 4 and 5 ofthe frame. Abrake operating lever 12 is fulcrumed intermediate its endson the front rod 11 and is designed to be held in adjusted the rod IOan-d its free end :iszconneotedwwith the loweriend ofleven 12'. by arod151to provide for the rocking of' rod: lO when. the lever 12 isactuated. ;Twoarms '16-.a-nd 1 7are "fixed to and :depend .from 'rod 10on: opposite sides ofathe arm 1 1 andospaced therefrom. Apairof rods 18and 19 are pivotally connected at their frontends with the fre'e endsoffithe arms .16-and;17 andv extend -rearwardly for connection withtl1e=.b1ake-. shoes 20 s and .21 which are exactly alike inconstructionithe lower faces or; gripping. faces :beingz-prefera bly.serrated as shown in=-F;ig. 24wat22. Mounted on the rear-axle. 23byiU-shapedclamps 24 or.- "otherwise, areiplates25uand 26 arranged belowtheaaxle nearwopposite ends thereof inside the rear wlheels'l3..Thesbrake shoes 2O and 21w=hich :are;pr efera'bly made 1 intheformofobtuse angle platesaaregpiv:

otally connected at their upper ends with the inner ends of the plates25 and 26. v The positioned so that they will engage the road bed whenthe shoes are lowered in a manner presently to be described.

Links 27 and 28 are pivotally connected and depend therefrom and arepivotally connected at their lower ends with other links 29 and 30 whichconnect with the upper faces of the brake shoes 20 and 21 said links 29and 30 being pivotally connected with said shoes. 7 p

The rods 18 and 19 have their rear ends outwardly offset and connectedwith the pivots which unite the links carried by'the plates and theshoes so that the longitudinal movement of these rods will operate toraise and lower the shoes, the forward movement operating to lower theshoes and the rearward movement to lift them.

braking faceslof these shoes shown at 22am In the use of this brakeshown in Fig.1

with the brake shoes in raised position the rearward movement of lever12 will operate to move rod 15 forward and rock shaft 10 causing thearms 16 and 17 to be moved rearwardly and the rods 18 and 19 connectedtherewith to be moved in the same direction. This forward movement ofthe rods 18 and 19 operate the toggle-like links which connect the shOes20 and 21 with the plates25 and 26 so that when said links arestraightened out the shoesare forced downward into braking engagementwith the road bed. This forcingof the brake shoes downward aroundwithout touching the road and the brake shoes owing to their engagementwith theroad bed will instantly stop the vehicle without skidding. Thebrakes may be locked in adjusted position by engagement of the pawl onlever 12 with the toothed quadrant 13.

- From the above description it will be obvious that these improvedbrake shoes may be used not only tostop'the vehicle but as j ack-s forraising the wheels :t'romthe ground when desired for any purpose andthat the parts may be locked in this position by the engagement of thepawl on the lever 12 with the quadrant'13.

This brake has only one rod for pulling the lever and thus obtainsgreater power with a less number of working parts. The constructionshown and described includes a rod for each brake shoe eliminating theuseof the rod directly beneath the differential. The pull exerted by therod 15 on the brake lever affords a triple leverage thus rendering itcomparatively easy to lift-the weight of the vehicle. 1

The gripping faces 22 of the brake shoes are preferably made separablefrom the shoesproper so that they maybe constructed of softer metal thanthe shoes and replaced when worn. r

I claim In combination with the rear axle and frame of a motor vehicle,a brake including substantially longplates secured to the axle andsupported thereunder, each of said plates having a forwardly anddownwardly extended end portion, a link pivotally con nected witheach'plate at the opposite end thereof, a link pivotally connected'witheach of the first mentioned links, brake shoesihaving ground engagingportions and having one of their respective ends pivotally connectedwith the forwardly and downwardly extended ends'of the plates, the lastmentioned links beingconnected with the-brake shoes at points adjacentto the opposite ends thereof, operating rods pivotally connected withthe frame of the vehicle and having pivotal connection with the links attheir points of pivotal connection for moving the ground engagingportions of the brake shoes THOMAS H.
